AutoGen is a tool designed for generating program
files that contain repetitive text with varied
substitutions. Its goal is to simplify the
maintenance of programs that contain large amounts
of repetitious text. This is especially valuable
if there are several blocks of such text that must
be kept synchronized. Output is specified with a
Scheme-enhanced output template. Input, if
required by your template, may come from AutoGen
definitions, CGI data, or XML files.

CGIProxy is a Perl CGI script that acts as an Internet proxy. Through it, you can retrieve resources that may be inaccessible from your own machine. The user is kept as anonymous as possible from any servers. HTTP and FTP are supported, and optionally SSL. Common uses include censorship circumvention, VPN-like setups, anonymous proxies, personal proxies, and others. Options include text-only browsing (to save bandwidth), selective cookie and script removal, simple ad filtering, access restriction by server, encoded target URLs and cookies, configuration by end user, and much more (currently over 70 config options). Javascript and Flash are fully supported. Messages are in 12 languages so far. Can be installed as a CGI script, a mod_perl script, a FastCGI script, or with its own embedded secure HTTP server. An online demo is available.

DBMEdit is a web-based DBM database editor (in Perl 5). If you use DBM files and don't have a simple way to edit them, you'll want this. It treats each element in the DBM as several fields joined by a delimiter, in effect supporting multiple columns within the single-column DBM format. DBMEdit displays your DBM database as a table, and provides auto-sized forms to add or edit records. Multi- user access is safe.
